Steve, I'm with Tim on this one - I will follow your lead.

Probably either Gray or Simple streams will be better than rolling our
own, unless maybe we can make a "best of both" setup.

Concerns that pop into my head, in no particular order:

1)  The copyright statement on the Allegro simple streams documentation
doesn't seem to have anything that gives permission for any use, and I
assume the Simple Streams code is present only in Allegro at the
moment.  Would it be worthwhile to contact Franz and see if they would
consider making the Simple Streams code part of their open source
effort?  Re-doing a simple streams library for generic CL would require
redoing both documentation and code, as it stands now.

2)  Are there libraries out there using gray streams that we would be
interesting in using and need to convert to simple streams?  If so, how
hard would that be?

3)  Would such a library implemented for GCL need to be GCL specific,
or could it rest atop ANSI CL?

Cheers, and thanks for looking into this!
